Description
The technical field is as follows:
the invention relates to a hollow building block for a wall body without grooving, belongs to the technical field of production of building materials, and particularly relates to a building block for a non-bearing inner wall body and a non-bearing outer wall body of a building.
Background art:
the wall body built by the concrete hollow blocks is always slotted and perforated because water and electricity pipelines need to be buried in a concealed manner, so that the anti-seismic performance of the wall body is greatly reduced. The current hollow block technical regulation requires that the hollow block wall body is prevented from being punched and gouged, but the method cannot be used in practice. The appearance of the wall surface after the groove is formed in the hollow block wall body can be formed by tragic traditions, and people can not believe that the wall surface can meet the earthquake-resistant requirement through visual perception. The hollow blocks have now been substantially replaced by aerated concrete blocks. In recent years, with the improvement of environmental protection requirements, the state requires the resource utilization of construction waste (including construction residue soil). The environmental protection department does not allow the building muck to be sintered into lightweight aggregates such as ceramsite and the like and then be made into bricks, the common solid bricks are too heavy and can increase the load of the building, and the current specifications do not allow the common solid bricks to be used for medium and high-rise buildings.
The existing concrete hollow block generally has two through holes, and two holes in a wall body are arranged along the direction of the wall body, so that the concrete hollow block is called as a single-row-hole block. When in building, the building blocks can be staggered and built with the next building block and aligned with the holes of the next building block. Therefore, a row of vertical through holes uniformly distributed in the wall body can be formed in the built wall body, namely the hollow wall body with the vertical through holes is formed. This is advantageous for reducing the weight of the building body and saving resources. However, in the decoration of building houses, no matter what kind of wall body is, grooving and punching on the wall body and installing water and electricity pipelines are almost inevitable. The existing concrete hollow block wall body has the advantage that due to the hollow structure inside the concrete hollow block wall body, the anti-seismic performance after the groove is formed in the wall body is greatly reduced. And because the groove on the hollow wall is communicated with the hole of the building block, the plugging is difficult. In urban residential construction, architects and construction units are reluctant to use concrete hollow blocks no matter how mature they are technically and of quality meet national standards, and in fact have been largely replaced by solid aerated concrete blocks in most areas. However, as the environmental protection requirement is increased in recent years, the state requires the construction waste (including the construction waste) to be fully utilized, and for environmental protection, the construction waste is not allowed to be burned into light aggregate such as ceramsite and the like to be made into solid bricks in policy, the density of the solid blocks which are not the light aggregate is high, the load of the building can be increased, and the solid blocks cannot be adopted by architects. Therefore, there is a need to develop a hollow block with a new structure, which can be accepted by the industry, and can be really applied to the building.
The invention content is as follows:
